Oh, I don't see any hint of argument here, just a good discussion of what we like and why
Personally, I think it is a serious problem. Yeah, they might be great cutters, but if their disposition is so scattered, what job could they hope to have after their years of cutting? If they are that touchy, they wouldn't make good novice or youth horses (like many good cutters do when they start to slow down a bit and aren't at the top of their game anymore), they would never survive ranch work without stressing themselves into a constant state of panic, most of them wouldn't even make good trail horses because you can't trust them not to freak at every new thing that pops up.
Plus, people don't stop to think that not all farriers are like you and my brother, not all of them are willing to work with a horse that is difficult or skittish. There are a lot of farriers that will flat out refuse a horse that won't stand perfectly still the entire time.
For me, breeding/training for horses that are naturally so goosey that they pretty much can't have a life outside of the cutting pen is on par with breeding racehorses with crappy feet and chicken bones. Yep, they might be good at one particular job, but they they aren't worth a **** anywhere else.
The horse that I was discussing earlier, Pokey, wouldn't have had a chance with anyone that didn't match up to my Dad's knowledge and ability. Hell, I know
I wouldn't have been able to get him broke. But, I also know that no matter how nice a horse he may be for us, we could never confidently sell him as a riding horse because somebody that knew just a little bit of something about nice
horses would get themselves killed trying to mess with him.
I don't consider that a good trait, even if he is a crackerjack cutter
